摘要	The primary crystallization kinetics of an Al(85)Ni(5)y(8)Co(2) amorphous alloy was studied by differential scanning calorimetry, in situ electrical resistance measurement and high-resolution electron microscopy. It was identified that a glass transition occurs clearly prior to onset of primary crystallization although some pre-existing nuclei do exist in this glass. Interestingly, the nucleation and growth kinetics of the primary Al nanocrystals proceeds at largely separated stages. The growth of the quenched-in nuclei of Al occurs predominantly well below glass transition temperature (T-g) followed by a high density nucleation in the remaining amorphous matrix near T-g and finally growth of all nuclei developed before.
